Caffeine comes from the German word kaffee and the French word cafe. They both mean coffee. Caffeine is completely absorbed in the body within 30 to 45 minutes and the effects normally lessen in three hours. Caffeine affects the mood, stamina, the gastric and colon activity and the cerebral vascular system of the body.

Is it addictive?

That depends on whom you ask. Some researchers found that the effects of caffeine withdrawal included a wide range of symptoms including headaches, tiredness, depressed mood, difficulty concentrating, drowsiness or sleepiness, irritability and other similar symptoms. The symptoms began within 12 to 24 hours after abstaining from caffeine products and lasted any where from 2 to 9 days. This amount of time shows evidence that some may be addicted to caffeine.

Other research, however, has found that caffeine is not addictive. The research shows that we have a desire to repeatedly consume caffeine merely for pleasurable reasons such as the aroma, taste and social aspects of consuming caffeine. They believe caffeine product consumption is simply a habit and not a need.

So whether you drink caffeinated beverages in moderation to boost your alertness or consume only a small amount for the taste, you should know the effects it may have on your body.
